Can not create a graphic

[wetterfrosch]

Hallo,
i can't create a graphic.

I get as example this error-message:
plot '< /srv/www/cgi-bin/goto.cgi th0-min5 2008090400000000' using 1:2 axis x1y1 title "Temperatur" with lines linecolor rgb "#ff0000", '< /srv/www/cgi-bin/goto.cgi th0-min5 2008090400000000' using 1:5 axis x1y1 title "Taupunkt" with lines linecolor rgb "#00c000", '< /srv/www/cgi-bin/goto.cgi thb0-min5 2008090400000000' using 1:11 axis x1y2 title "Luftdruck" with lines linecolor rgb "#0080ff"

The important error you are seeing is "all points y value undefined!" which means there is a problem setting up the y-axis. (if it was a data error you'd see "all points x-value undefined" )

It appears that the Meteohub is not reporting the minimum and maximum values for the data over the time period you are trying to draw, or your custom settings have incorrectly overwritten the defaults that the program sends.

You could try manually specifying the y-min and y-max values on the graph definition page and see if that remedies the problem, and try to debug it from there...
